Fibre upload speed has dropped recently

I've been on an Ultra Fast 100 fibre plan for about six months. From a laptop via wifi, at installation I was getting about 80 Mbps download and 20 Mbps upload speeds. This evening my family complained of slow upload speeds; I tested, rebooted the modem, and tested again and see 80 Mbps download and 4 Mbps upload. This is a huge drop in upload speed.

I've verified that none of my devices should be affecting the upload speed. Is this a network problem?

Re: Fibre upload speed has dropped recently

I tested today on wired desktop and wireless laptop and was able to reach about 16-18 Mbps upload speeds each time, and the usual ~80 Mbps download speed (I wish I could get up to the 100 Mbps spec!). Whatever the problem was, it seems to be fixed now. Thanks!

You should be getting the speed you're paying for, if you are on fiber 100 then 100 down is what you should be getting not 80...

Have you ever read the Ts and Cs for a broadband service? VF's are below.

Your broadband speed will vary depending on a number of factors including NZ and overseas networks, your modem and computer technology including wifi capability, internal home wiring, other environmental factors, and how many other people are using it at the time.

Best to check your computers network adaptor to see if it's gigabit vs 100mbps, this would cause the max speed you can get to be lower tha what the plan offers. Also open task manager and click the performance tab. Monitor the CPU and Memory graphs to see if they're spiking during the speedtest.

I have fibre at home too, same setup, and I generally get 99-101mbps on wired speedtest.

I am getting the Full 100 down, But I have a new computer and a decent router both have Gigabit Lan and I test over ethernet. Home wiring isin't really an issue anymore on fiber because you arn't using it for fiber, the only home wiring would be if you have ethernet all through your house and it's getting signal loss.

Re: Fibre upload speed has dropped recently

My wired test was from a computer with ample CPU and memory and a Gigabit Ethernet port connected to the fibre modem through a Gigabit switch. I got identical results from my wireless tests as well, sitting in the same room as the modem and using the 5 GHz network band.

Is there something Vodafone can do to check the speed on my fibre line? I remember several rounds of tests when I had VDSL installed as the speed for that was much lower than expected, but I agree that with the new fibre infrastructure, all should be well and fast now.

I wander what you would get if you changed to the 200 plan,

Because like I said you should be getting 100% of the speed you're paying for. have you tried testing with different ethernet cables? Also make sure you are the only one using the internet when your doing the tests, and make sure you haven't got anything running in the background i.e Steam updates/ utorrent

Re: Fibre upload speed has dropped recently

I, too, have often wondered what kind of speed I would get on the 200 Mbps fibre plan, but not enough to go through changing my plan to try it out.

When I get a suspicious speed test result, I always stop any background processes, and reboot the fibre modem and test again when it has reconnected to the Internet - so the chance of someone/something else using the network is minimised. I've done that in this case and it hasn't changed the download speed beyond 80-85 Mbps.
